Question

Literally putting this at 45 points. can someone help me please

Answer 1

• 15.4%

Explanation:

Volume of a cylinder:

• V = πr²h

Container A

• r = 10 ft, h = 11 ft
• V = π*10²*11 = 1100π ft

Container B

• r = 7 ft, h = 19 ft
• V = π*7²*19 = 931π ft²

After pump out the container A has the level of:

• 1100π - 931π = 169π

Level % in the container A:

• 169π/1100π×100% = 15.4% rounded to the nearest tenth
